What does a change in the red reflex during an eye examination suggest?

A change in the red reflex during an eye examination indicates potential cataracts or ocular abnormalities because the red reflex is a reflection of light off the retina as seen through the pupil. Normally, the red reflex should appear uniformly bright. If there is a cloudiness or absence of the red reflex, it may suggest conditions such as cataracts, which scatter light and inhibit the clear reflection, or other ocular issues like retinal detachment or tumors.

This observation is critical in pediatric examinations, as it can reveal serious conditions that may not yet have symptoms. Recognizing changes in the red reflex allows for early intervention and management of any underlying problems, making it a vital aspect of a comprehensive eye examination.
